TRAVELING HARVESTER.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed October 23, 1912. Serial No. 727,354.

To all whom it may concern:

Be it known that I, FRANK 5. Homer, a citizen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia, have invented new and useful Improvements in TravelingHarvesters, of which the following is a specification.

This invention relates to traveling harvesters.

The object of the present invention is to provide in a harvester havingthe usual seliiarating or threshing n'iechanism and a header, meanswhereby said mechanism and the header can be driven when the vehicle ishorse propelled, or which may be driven by a motor, such as a gasengine, mounted on the apparatus; the driving mechanism including suchelements that either the motor may be selected to drive the threshingmechanism and header, or power to drive the same may be derived from themain traction wheel or wheels.

In practice it is frequently advantageous to be able to select eitherthe motor or the traction wheel under certain conditions to operate thecutting, feeding and threshing mechanisms. Thus in order to still drivethe threshing mechanism .in the event of the stopping of the machine isdown or heavy lodged grain, it is necessary to have the motor. At othertin'ies when the machine working in thin grain and the draft on theanimals is comparatively light, it may be more economical or advisableto run the machinery from the main supporting wheel or bull-wheel of themachine.

The invention consists in combination with a traveling harvester, ofalternative means for driving the threshing mechanism and the header ofthe harvester from an independent motor on the harvester frame, or fromthe traction wheel of the machine, with mechanism for selectivelyconnecting the traction Wheel to the driving mechanism or connecting themotor thereto.

It also comprises details of (:(mstruction which will be more fullyexplained by reference to the accomimnying drawings, in which Figure 1.is a side elevation of the improved harvester. Fig. 2 is a rear end viewpartly in section. Fig. 3 is a diagramu'nltic, plan view of thetransmission.

In its illustrated embodiment 2 represents the housing for the threshingand cleaning mechanisms of the harvester, which is mounted upon suitablesills or frame 3. At the forward end of the frame 3 is a steering wheel5, to which may be attached suitable traction means, as a team of horsesor traetion engine.

(3 is a suitable traction wheel or wheels carrying the main part of theload.

The threshing cylinder 7 is mounted upon a shaft 8 appropriatelyjournaled in the housing. One end. of the shaft projects through thehousing and carries a pinion 9, meshing with and driven by an internalgear 10, attached to or forming a part of a sprocket wheel .11 securedon the countershaft or jack-shaft 12. Also secured on the countershaft12, at its outer end, is a sprocket 13.

My invention relates particularly to means whereby the threshing andsepa 'ating mcclninism, including the cylinder 7, may be driven eitherfrom the main traction wheel (3, or by a suitable motor 14; mounted onthe harvester frame. As shown, motor 14: has a shaft 1.55 -arrying ally-whecl 16 which may be loose upon the shaft 15 and coupled thereto,when desired, by a suitable clutch l7. Secured to or formed with thefly-wheel 16 is a sprocket pinion 18, driving a sprocket chain It) whichruns to and drives the sprocket wheel which is fastened upon thecountcrshaft 12. From this it will be seen that when the motor l-l isrunning, if it is desired to operate the threshing mechanism thereby,the clutch 17 is manipulated to connect the fly-wheel l0 to the engineshaft, so that the power of the engine will be transmitted by thesprocket chain it), or other equivalent mechanism, to and drive thecolmtershaft 12. This in turn, through the internal gear 10, drives thepinion 9 and the cylimler shaft 8.

From the countcrshaft 12 power is transmitted by the pinion 13 by meansof a sprocket chain 20, running from the pinion l to and driving amaster sprocket 21 which is secured on the outer end of an. intermediatemain shaft 222 projecting from one side of the housing 2 and supportedon the frame 3. Also mounted on the intermediate main shaft 22 asprocket. pinion 2 this being normally loose on the shaft and having aclutch fare A l: which may be coupled to a slidablc clutch jaw 25 kevedon the shaft 2 when it is desired to cause the sprocket pinion 23 to bepositively connected to the shaft 22. The purpose of the sprocket pinion23 is to derive power through a sprocket chain connection 26 from adriver or sprocket ring 27, which is secured to or formed upon one ofthe traction wheels 6.

It will be seen that if the vehicle be horsepropelled and conditions aresuch that the machine can move along steadily and continually at uniformspeed so as to run the cylinder and cutting mechanism at proper speed,and the draft is not too great on the team, I disconnect the motor 14and connect the threshing cylinder with the traction wheel 6 by clutch25. The motor 1% may be disconnected by releasing the clutch 17whereupon by throwing in the clutch jaw 25 to positively engage thesprocket wheel clutch 24:, power will be derived from the traction wheelthrough means of its connected sprocket driver 27. This power deliveredto and rotating the shaft 22 will be imparted, by reason of the sprocketwheels and chain 21, 13 and 20, respectively, so that the countershaft-12 will be driven from the wheel 6 as will the remaining part of thethreshing and cutting mechanisms, which are not necessary here todescribe or shown in detail.

The driving means for the separator comprises the sprocket shaft 22, asprocket wheel 28 keyed thereon, and a chain 29 running on the sprocketwheel 28 and traveling over and driving other sprocket wheels 30 whichtransmit their motion to the separating mechanism. within the housing 2.Power is transmitted from the sprocket shaft 22 to drive the header orcutting mechanism by the following means: Secured upon the sprocketshaft 22 is a sprocket wheel 31, driving a sprocket chain 32 engaging asprocket pinion 33 secured on a cross-shaft 34. The cross-shaft 34Lextends transversely across the rear end of the housing 2 and carries onits opposite end a pinion gear 35, meshing with and driving acorresponding gear 36 which is fast on a short shaft 37; the shaft 37extending parallel to the har vester frame, as shown in Fig. 3. Thelongitudinal shaft 37 carries a sprocket pinion 38 which drives atransversely extending sprocket chain 39 which extends outwardly anddrives a sprocket pinion 40, secured on a pinion shaft 41; this shaftbeing appropriately mounted in a bearing or bracket frame 42 attached tothe contiguous portion of a wheel and header frame 3, which is shown ashinged by a parallel link structure 43 to the main frame of theharvester, by which the threshing mechanism may be maintained alwayshorizontal, even when the machine is working on a side hill. Preferablythe short, longitudinal shaft 37 is arranged in close proximity to thepivots of the link structure 43, adjacent to the side of the mainhousing 2, so that the sprocket chain 39 will automatically compensateand accommodate itself to the angular position or adjustment of thewheel frame 3 to the main body 2 during operation on a hillside. Theshaft 4-3 carries a pinion 4:4: meshing with a corresponding pinion 45fast on the shaft 1-1 and also carries a driving sprocket atti, drivinga chain 47 which runs forwardly and drives the header mechanismindicated generally at 48. There is provided, and may be used to derivepower, the wheel 6 on the grain side of the machine and the driversprocket 27 over which may be run a chain 26 to drive a sprocket 21 onthe header countershaft; the chain 26 being removed during the operationof the vehicle by the engine 14:. By throwing out engine clutch andthrowing in clutch on the main wheel countershaft, the machine isconverted into what is termed a horse propelled. harvester. Many timesit has been found ad vantageous to shift from one to the other in caseof accident. If the gas engine fails to furnish power for driving theseparator, the clutch 25 on the main separator shaft is allowed toengage with the sprocket 23, causing a continuous drive of all parts ofthe separator, independent of the gas engine; the main driving wheeltaking traction from the ground in the usual manner of such machines. Inorder that the engine may be positively connected to and drive thetraction wheel 6, shaft 22 is provided with a splined clutch jaw 23which is 'shiftable into engagement with the complementary side of thesprocket wheel 23 when the vehicle is to be 1notor-propelled. Toequalize the traction drive on both traction wheels 6, a clutch 43 issplined on shaft 43 and is engageable with the sprocket wheel 21 todrive wheel 6 with driver sprocket 27.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. In a traveling threshing machine provided with amotor, a countershaft to the rear of said motor, a main shaft at therear of said threshing machine, a main bearing wheel shaft locatedsubstantially intermediate said counter shaft and main shaft, 21 mainbearing wheel on said bearing wheel shaft, a threshing cylinder havingdriving connection with said counter shaft, and a separator havingclutch connection with the motor and with the bearing wheel so as toderive power from either alone or concom' itantly from both.
